Final answer:
Jupiter is significantly larger than Saturn.
Step-by-step explanation:
Jupiter is 318 times more massive than Earth and Saturn is about 25% as massive as Jupiter. To compare the sizes of Jupiter and Saturn, we can use their diameters. Jupiter's diameter is 11 times that of Earth, while Saturn's diameter is about 10 times smaller than the sun's. Since Jupiter is larger than Saturn and 11 times the size of Earth, we can conclude that Jupiter is significantly larger than Saturn.
